But that's the thing, though -- does he *need* it? Would he live if he doesn't get grade skipped? Sure. He'd probably be just fine. Would he be challenged with his schoolwork? No. Would he learn good study habits? No, probably not, though he still might. Do I think it'd be better to skip him? Absolutely. Do I think he'd socially and emotionally do great with a skip? Yep, I do.
But I'm not convinced that it's the only way to educational fulfillment. Maybe that's why I'm looking for more confirmation that he really is that out there with the SB L-M. I think he is, and his WPPSI and WIAT results seem to confirm that. So I should probably just leave well enough alone and go with what we've got, which is nothing to sneeze at.
Clearly your son's scores say that he could easily handle a skip or 2 or 3, academically. But the decision to skip is way more than whether one can handle it academically. As I have said, I was skipped, and it provided little challenge academically but it was socially disruptive. My son (in 6th) just took a practice ACT and those scores show he has higher scores than the average entering freshmen at many mid-tier colleges. But he is not skipped, nor have we seriously considered a skip. His school is open to subject accelerating and he has many friends and activities he loves that he does not want to disrupt. It is not a great school (by the numbers), but they have been great to him!
In my mind, you skip a child because there is a problem. I am constantly looking for problems, but we haven't had any we have needed to solve by skipping. Others have not been as lucky with their schools, or have kids that have a personality that would thrive on skipping. Or they really need it to stay engaged. For them, it's a good solution.
So I guess what I'm saying is that you son has the numbers to be able to handle the skip academically, but how does everything else stack up? Are there things in the school that you'd hate to have him miss out on a year of? (DS had the most fabulous PE teacher you could imagine and I hated the idea that he'd miss a year of that. Through my childhood, I remember wondering what I missed by never going on the first grade field trip, myself). Basically, if you skip, you are making a trade. Is the trade worth it? For some it is, other it isn't. But those answers don't come from the numbers.
